As steel fiber is added to high shength concrete, the value of ductility coefficient increases 41. 3 %, and the ultimate compression stain increases 30.6%.
在各项条件基本相同的情况下，由于钢纤维的作用对延性系数的提高幅度达41．3％，对极限压应变的提高幅度达30．6％。
If a iterative coefficient is added to the formula used to adjust apparent resistivity, the calculated value will rapidly access to observation value, therefore the number of iteration is lowered.
在调整视电阻率的公式中加入一个迭代系数，可使计算值快速趋向于观测值，减少了迭代次数；
